Boston Mayor Marty Walsh announced Friday the results of a study that evaluated community exposure to COVID-19.
Of the Boston residents tested, 9.9% tested positive for antibodies, and 2.6% of those tested who were asymptomatic tested positive for COVID-19.
About 1 in 10 residents in the study have developed antibodies, and about 1 in 40 currently asymptomatic individuals are positive for COVID-19 and potentially infectious.
“We can draw two preliminary conclusions from the results of this study,” Walsh said “First, that the actions we took early on in this pandemic made a real difference in slowing the spread and, second, that the majority of our population still have not been exposed to the virus.”
Walsh stressed officials need to move cautiously as they look to reopen the city.
